3 Claims.

This invention relates to a power-operated brush, and more particularly to a cleaning brush adapted for use in currying and cleaning cattle and other animals.

An object of this invention is to provide a novel currying brush which can be readily used for cleaning and brushing cattle, horses, and other animals, and which has means for easily removing the brushes thereof for ready replacement for cleaning.

Another object of the invention is to provide means for readily and safely applying a poweroperated brush to the hide of cattle, horses, or the like, which brush may be readily powered by an electric motor and which is easily carried from place to place.

Yet another object of the invention is to provide an electric brush with means for readily substituting a cylindrical brush for another brush when such other is in need of cleaning. It is also contemplated to use this device as means for removing paint or rust, cleaning butchers blocks, and. performing various and other sundry duties as can be readily understood.

Still further objects of the invention reside in the provision of an electric currier that is strong, durable, highly efficient in operation, simple in construction and manufacture, self-powered, easy to use, relatively inexpensive, and quite pleasing in appearance.

These, together with the various and ancillary objects of the invention which will become apparent as the following description proceeds, are attained by this electric currier, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings wherein:

Figure 1 is a side elevational view of the electric currier comprising the present invention, with the cap removed and parts of the device being shown in section for greater detail thereof;

Figure 2 is a vertical sectional view as taken along line 2-2 in Figure 1;

Figure 3 is an exploded perspective view of the electric currier, showing the various elements thereof in detail.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral I is used to generally designate the electric currier comprising the present invention. This electric currier comprises a housing l2 including a cylindrical casing l5 in which an electric motor [3 is suitably emplaced, the drive shaft of which motor extends outwardly from the casing and is designated by reference numeral l4. Y The housing l2 comprises an upper portion having a downwardly curved overhanging edge It and integrally formed side portions I8 and 20. A handle 22 is integrally formed with the top portion of the housing l2 and by means of set screw 24 a three-speed switch is secured at the inner portion of the handle for ready engagement by the fingers of the operator and is connected through suitable electric conduits 28 to the electric motor for control of the speed of the brush.

Integrally molded with the'sides i8 and 20 of the housing I2 are rings 30 and 32 which retain by means of set screws 34, annular bearing races 36 and 38 each of which are provided with an annular groove 40 and 42 respectively for retention therein of ball bearings 44. These ball bearings are elsewise retained within the peripheral annular grooves 46 and 48 of disks 50 and 52 each of which are provided with spacedapertures 54' therethrough for a purpose presently to be set forth. Inwardly extending portions of the walls 18 and 20 provide flanges 3i and 33 for properly locating the races 35 and 38 in the rings 30 and 32 respectively.

By means of set screws 56 engageable within the recesses 54, a cylindrical brush generally indicated by reference numeral 58 may be secured to the oppositely disposed disks 50 and 52 respectively. These screws are readily engaged within suitable recesses 60 in the cylindrical portion 62 of the brush to which the bristles or wire hairs 64 are suitably attached. The brush is rotated by means of a V-shaped belt 66 which translates the rotary motion of shaft l4 through pulley wheel 68 on shaft l4 and pulley wheel 'Hl secured to shaft 12 which is rigidly connected to the disk 52. Lock means 14 of conventional design are used to hold the pulley wheels 68 and 10 on their respective shafts.

The lock means 14 are preferably formed integrally with the pulley wheels and set screws 16 are used to rigidly secure the lock means and pulleys to the shafts l4 and 12. A suitable molded cap 18 is provided which has a pleasing external configuration and is internally shaped so as to be easily fitted over the ring 32 which is provided with spaced recesses 30 in which spring clips 82 secured to the inner surface of the cap 18 may be selectively engaged. An annular protector 84 is secured to the cap 18 by means of rivets 86 so as to prevent dirt, dust, or the like, or por- 3 tions of the V-belt 65 from being caught between the bearing race 38 and the disk 52.

A conventional plug, not shown, which is connected to an extension cord 88 which in turn is connected to the electric motor is provided for connection to a suitable outlet connected to a source of electric power supply.

By selective operation of the switch 26, the brush 58' may be rotated at a desired speed and easily applied by holding handle 22 firmly to the side of a cow or other animal. Bristles 64' on the cylinder 62 may be made of any suitable strength so as to be able to perform a desired function. The cylinders are readily exchanged by merely removing the screws 55 from the disks and cylinder 62.

Since from the foregoing, the construction and advantages of this electric currier are readily ap- 4 in said casing and having a shaft extending out of the open end thereof, a brush having a longitudinally extending hub, the length of said hub being equal to the spacing between said bearing rings, a disk having a peripheral groove therein disposed in each of said rings concentrically thereof, a bearing race in each of said rings, each of said races having a complementary groove in the inner face thereof, anti-friction bearing elements disposed in said grooves and rotatably mounting said disks in said rings, fasteners securing each of said disks to the relatively opposite ends of said hub, a stub shaft on one of said disks, a belt drivingly connecting said stub shaft to said motor shaft, and a dished cap overlying said stub shaft and having a rim detachrings.

parent, further description is believed to be uh- I necessary.

However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit th invention to the precise embodiment shown and described, but all suitable modifications and equivalents of this power brush may be readily resorted to. which fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A power brush comprising a housing having a top wall, a. cylindrical motor casing integral with said top wall and opening at one side of said housing, a pair of axially aligned bearing rings each integral with the relatively opposite sides of said housing with the axis of the rings paralleling the axis of the motor casing, a motor disposed in said casing and having a shaft extending. out of the. open end thereof, a brush having a longitudinally extending hub, the length of said hub being equal to the spacing between said bearing rings, a disk having a peripheral groove. therein disposed in each of said rings concentrically thereof, a bearing race seated in each of said rings, each of said races having a complementary groove in the inner face thereof, anti-frictionbearing elements disposed in said grooves androtatably mounting said disks in said rings, fasteners securing each of said disks to the relatively opposite ends of said hub, and means drivingly connecting one of said disks to said motor shaft.
